and dash position indicated in the same figure.

It will be noted that the lower end of the discharge nozzle is provided with both internal and external screw threads. This provision is so that, if desired, a plug may be substituted for the cap D and secured to the lower end of the dischargenozzle by screw connection-with the interior thereof, instead of by connection with the exterior, as shown. Both types of closure are common in the art, but only one is illustrated in the drawings.

What I claim is: 1. In combination in a device of the character described, a shipping or storage vessol, a support therefor, a discharge pipe or nozzle communicating with the interior bottom portion of said vessel, oscillatory means mounted on said vessel-support at a distanec from said nozzle and having spaced lower portions, a cap-retainer connecting said spaced portions. a cap rotatable in said retainer, said means being movable into unbalanced position to locate said cap for attachmcnt to the lower portion of said nozzle and reversely movable to remove the cap ,from the discharge path when it is detached.

2. In combination in a device of the character described, supporting girders, a tank mounted thereabove, adischarge nozzle communicating with the interior of the tank and depending between said girders to' be protected thereby, a cap for attachment to said nozzle below said girders, and a loosely connected cap support having opposite terminal portions connected to different girders and an intermediate portion loosely mounting said cap, said cap-support being hung at a distance from said nozzle but be ing movable toward the nozzle into an unbalanced position, said cap when disconnected-.from said nozzle moving with its support to fall to one side of the discharge end of said nozzle.

3. In combination in a device of the character described, a shipping or storage vesscl, a support. therefor, a discharge nozzle communicating with the interior of said vessel through the bottom portion thereof, a closure'adapted to be rotatably secured to the lower end portion of said discharge nozzle, and a swaying structure of substantial rigidity connected with said vessel-support to swing away from but movable toward said nozzle and including separated portions loosely connected by a closure-holder rotatably mounting said closure, said swaying structure being adapted to. swing said'cap to one side of said nozzle when the cap is disconnected therefrom.

r. In combination in a device of the character described, a shipping and storage vessel, a support therefor, a discharge nozzle communicating with the interior of said vessel and depending below said support, a closure for the discharge end of said nozzle and an ecccntrically mounted closure-carrier comprising spaced oscillatory arms connected with said support and a closure-retainerconneeting said arms. y

In combination, a shipping or storage vessel, a structure underlying and supporting the same, a discharge nozzle for said vessel depending thercbelow, a closure for the lower end of said nozzle, means encircling said closure, and means of substantial rigidity having oscillatory support from the vessel-supporting means at a side of said nozzle and movable to be unbalanced to carry said closure into juxtaposition to said nozzle, and rcvcrsely movable to permit the closure to be swung to and supported at one side of said discharge nozzle when the closure is released therefrom.

6. In combination in a device of the character described, a shipping ,or storage vessol, spaced sills supporting the same, a dis of the .ischarge nozzle when. disconnected therefrom.

7 In combination in a device of the char acter described, a shipping or storage vessol, spaced sills supporting the same, a discharge nozzle extending between said silis, a closure for the lower end of said nozzle,

- and a suspended closure-carrier comprising arms depending from and pivotally connected to said sills and a cross member connecting said arms and mounting said closure to be moved for attachment to said nozzle, said closure-carrier being inclined against granity when said closure is connected to said nozzle and being adapted to swing said,

closure away from said nozzle when it is disconnected therefrom.

8. In combination in a device "of the character described, a tank, a discharge nozzle depending below said tank, a closure for the nozzle, a support spaced from and independent of said'nozzle, and a closure-carrier of substantial rigidity having a plurality of pivotal connections with said. support at one side of said nozzle, whereby opposing reaction from its different pivotal connections causes said closure to have s prescribed path of movement, and also being movable toward said nozzle into unbalanced position, said closure being operably :nonnted in said carrier for connection to said nozzle and said carrier being adapted to positively carry said closure in the prescribed path to one side of said nozzle when disconnected therefrom.

9. In combination in a. device of the char acter described, a tank, a discharge nozzle depending below said tank, a closure for the nozzle, a support spaced from and inde pendent of said nozzle, and a closure-carrier comprising spaced rigid members pivoted to said support and a cross member roclzably attached to said pivoted members and mounting said closure for connection to said lower portion of the nozzle, said carrier being adapted to be inclined toward said nozzle and operable by gravity to positively carry said closure in a predetermined path carry the way from said nozzle when it is discontheretrom, said closure being l0l- 'ts carrier.

am: and discharge nozzle detlierefroxn, in combination with a Cap ,or said nozzle, a support and. a gravity operable yoke pirotally connected. to said support at a distance from said nozzle and including a cap-retainer and pernlentn1e1nbers of substantial rigidity connected therewith continuously holding said retainer in approximate horizontal position when disconnected from the nozzle, said yoke being movable toward said nozzle into unbalanced position and l'ie'ng adapted to positively 1 y from the nozzle when it is dieting therefrom.

In witness whereof I have hereunto set my band in the presence of two Witnesses.
